Decorative Concrete - Pinstripe Aggregate

Introduction: Decorative Concrete - Pinstripe Aggregate

The pinstripe aggregate method uses corrugated craft board to help achieve a pinstripe pattern of exposed and unexposed aggregate.

The craft board creates a corrugated pattern in the surface of the concrete. After the concrete is set, the hills are ground down to expose the aggregate, but the valleys remain un-ground, creating contrasting lines of exposed aggregate and lines of no exposed aggregate.

In this instructable, I also added some white paint to the valleys to help highlight the effect.
